2006 Chevrolet TrailBlazer LT 4dr SUV 4WD (4.2L 6cyl 4A)
I currently have 23,000 miles on my 2006 trailblazer. My check engine light came on, and they said it was misfiring in the cylinders. They replaced one, but that didn't fix it. Gm told them to replace the whole head and gaskets. They billed gm for over $6,000 warranty work, and now the light is on again. They are saying it is a parts problem, but they have to order the same part again to put back in it..$6,000 more dollars. My warranty is up in 2 more months, and I am trading this vehicle. My cousin has one also, and has problems. The service manager told me that it was a problem with the in line 6 engine in this vehicle.
